A chap with some serious identity issues kidnaps a trio of teenagers and locks them in a basement for reasons unknown. As they plot and and cry and dither, there are some tense moments as they try to figure out how to get free.

James McAvoy’s character is supposed to have 23 personalities locked in there; we get to see eight of them and he shows them well; he’s both fun and terrifying to watch. This is a, “locked in a bunker” film, but unlike 10 Cloverfield Lane, there is no doubt as to the antagonist’s sanity. He’s clearly mad as a box of bats.

Shymalan had not impressed me lately, or in a long while, but he is in fine form here with a tight story and excellent direction. I hope he keeps this up, as this movie has possibilities of sequels.

There are no post credit scenes, so feel free to split when they roll. (See what I did there? Nyuk nyuk nyuk).
